Leftover Mashed Potato Cheese Puffs Ingredients
The magic of this dish truly lies in its harmony of flavors and textures. You’ll find that these ingredients meld together beautifully to create something special. Don’t worry about exact measurements just yet; those are all in the recipe card for you!
Essential Components
- 2 CUPS LEFTOVER MASHED POTATOES: These are the stars, providing a creamy base that forms the foundation of our puffs.
- 1 CUP SHREDDED CHEESE (CHEDDAR OR YOUR CHOICE): This little gem packs a mighty punch with melty goodness, bringing that indulgence we crave.
- 1/4 CUP GREEN ONIONS, CHOPPED: Adding a pop of freshness and crunch, these vibrant bits elevate the flavor profile.
- 1/2 CUP BREADCRUMBS: These give our puffs that essential crunch on the outside, ensuring a delightful contrast to the fluffy interior.
- 1 EGG: The binder that brings it all together, providing structure without being too dense.
- SALT AND PEPPER TO TASTE: Essential seasonings that enhance all the flavors.
- OIL FOR FRYING (IF FRYING) OR COOKING SPRAY (IF BAKING): This helps achieve that beautiful golden-brown exterior.
Substitutions and Tips
Want to switch things up? Here are some fun ideas:
- Cheese: Swap the shredded cheese for something like pepper jack for a spicy twist (though it won’t be quite as mild).
- Green Onions: Use fresh herbs like parsley or chives for a different flavor—freshness is key!
- Breadcrumbs: In a pinch, crushed crackers or panko can work wonders, offering that delightful crunch.
- Egg Alternative: If you’re looking to avoid eggs, a flaxseed egg works well, though your puffs may be less sturdy.
A little note: Cooking times can vary based on your method, so keep an eye on those lovely puffs as they bake or fry to ensure they don’t over-brown!
Kitchen Tools You’ll Need
- Large mixing bowl
- Baking sheet (or frying pan)
- Parchment paper (if baking)
- Measuring cups, spoons
- Mixing spoon or spatula
- Cooking spray (if baking)

How to Make Leftover Mashed Potato Cheese Puffs
Let’s dive into creating this wonderfully indulgent dish. I’ve broken down the process into simple steps. Follow along, and you’ll have a delicious meal in no time. We’re aiming for golden, crispy puffs full of comforting goodness!
Preheat and Prepare
First, preheat the oven to 400°F (200°C) if you’re opting to bake. This step is key to ensuring your puffs get that perfect crisp on the outside. Grab your baking sheet and line it with parchment paper; it’ll save you a mess later!
Combine the Stars
Next, in a large bowl, combine the leftover mashed potatoes, shredded cheese, green onions, breadcrumbs, egg, salt, and pepper. Mix until everything is well combined—feel free to use your hands here. It’s satisfying to feel the mixture come together!
Shape Into Puffs
Now, shape the mixture into small balls or puffs, about the size of a golf ball. It’s okay if they aren’t perfectly uniform; rustic is charming! Just remember, the key here is to pack them tightly so they hold their shape.
Prepare for Baking or Frying
Once shaped, if baking, place your puffs on the prepared baking sheet and give them a gentle spray with cooking spray. If frying, heat oil in a pan over medium heat, ensuring it’s hot enough to cook the puffs quickly without soaking them.
Bake to Golden Perfection
If baking, pop those beauties in the oven and let them bake for about 20 minutes or until they’re golden and crispy. If frying, carefully lower a few puffs into the hot oil, frying until golden brown on all sides. This step helps us achieve that delightful crunch!
Serve with Love
Finally, serve warm as a tasty snack, appetizer, or as a side dish alongside your favorite meal. Invite friends and family to share in the joy, and don’t forget to enjoy them straight out of the oven—there’s nothing quite like that first bite!
How to Store Leftover Mashed Potato Cheese Puffs
If you’re lucky enough to have any leftover puffs, they store well! At room temperature, enjoy them within a few hours. For refrigeration, pack them in an airtight container and keep them for about 3-4 days. If you want to save some for later, you’ll be pleased to know they freeze beautifully! Just store in the freezer for about 2-3 months, and when you’re ready to indulge, thaw them overnight in the fridge. To reheat, simply pop them in the oven on low for a few minutes until warmed through.
Tips for Success
- Use a thick layer of breadcrumbs for maximum crunch!
- Don’t overmix the potato mixture; gentle folding keeps them light.
- Experiment with different cheese types for unique flavor combinations.
- Try frying in small batches to avoid crowding the pan, which can lower the oil temperature.
Serving Suggestions
- Pair with a zesty dipping sauce like ranch or spicy mayo.
- Serve alongside a vibrant salad for a fresh contrast.
- Enjoy with a comforting warm soup on a chilly evening.
- Garnish with extra chopped green onions for a pop of color.
- Complement with a crisp white wine or a refreshing iced tea.
I hope you enjoy making these Leftover Mashed Potato Cheese Puffs as much as I do! They’re a comforting reminder that homemade food is all about creativity and love. Happy cooking!
